AUXILIARY AIR-SUPPLY DEVICE.

Specification o f Letter Patent Patented Feb. 11, 1919.

To all whom it may concern: 1

Be it known that I, CHARLES W. JENKINS, a citizen of the United States, residing at Ellerson, in the county of Hanover, and State of Virginia, have invented certain new and useful Improvements in Auxiliary Air-Supply Devices, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved auxiliary air supply device for gasolene engines, and has for its primary object to provide means mounted upon the dash board of the vehicle which may be readily controlled by ithe operator to supply atmospheric air to the gas supply pipe or manifold to reduce the richness of the gaseous mixture.

It is another important object of the invention to provide a device for the above.

purpose which is of such construction as to minimize the possibility of foreign matter being drawn into the engine cylinders, and which may also be employed for supplying water to the cylinders when they become overheated.

And it is a further general object of the invention to provide an accessory for motor vehicles as above characterized which consists of relatively few parts of simple form, and which may, therefore, be manufactured at comparatively small cost.

With the above and other objects in view, the invention consists in vthe improved construction, combination and relative arrangement of the variousparts as will be hereinafter more fully described, subsequently claimed and illustrated in the accompanying drawing in which similar reference characters designate corresponding parts throughout the several views, and wherein Figure 1 is a vertical sectional view illustrating the preferred embodiment of the invention;

Fig. 2 is a top plan view, aportion of the cap or cover being broken away;

Fig. 3 is a bottom plan view of the valve plate; and

Fig. 4 is a detail perspective view of the atomizin means.

.Refcrrmg in detail to the drawing, 5

designates the body of the device, which may be of aluminum, brass or other desired metal, and is formed with a tapering cylindrical enlargement or cup 6, which affords a chamber 7. The body of the device is furtherprovided with a bore 8 which communicates with the base of the chamber 7 at one side thereof. The body wall of said chamber is preferably internally formed with an annular shoulder or flange 9 to provide aseat for the perforated metal plate or disk 10, whereby said plate is spaced from the base wall of the chamber. The passage or bore'8 extends horizontally, and is in communication with the lower reduced end of a. vertical bore 11 formed in the body of the device. The upper end of this latter bore is permanently closed by the plug 12 having a reduced stem 13 extending downwardly and preferably tapered or pointed at its terminal, which terminates adjacent to the upper end of the reduced portion of said bore.

A laterally projecting hollow stem 14.- is integrally formed with the body 5 and communicates with the bore 11 adjacent its upper end. I This stem is exteriorly threaded for the connection of one end of a pipe 15 thereto. The other end of this pipe is tapped into one side of the engine manifold or connected to the gas supply conduit between .the manifold and the butterfly valve.

Within the chamber 7 awick or other suitable porous material indicated at 16, is disposed and rests upon the perforated plate 10. The wall of the chamber-7 is exteriorly provided at its upper end with a flange 17 the edge thereof with the inwardly projec'ting lugs 20 which are adapted for engagement through the notches or recesses 18 and with the inclined lower edges of the flanges 17 when the cap is turned in one the cover and the washer disk.

notches or recesses 18 into said chamber. The

top wall of the cover is provided in spaced relation 'to its center with an opening 23 which coincides with a similar opening '24: inthe' washer disk 22. A pin or Stud '25 is also fixedfin the topof the cover and upon thecover top a valve plate 26 is arranged.

This plate is mounted for turning movement upon a pin 27 suitablyfixed in the top: of An'ar'cua'te groove orchannel 28 is formed in the under side'of the valve plate to receive"the'lug 25-whichlimits therotation of said plate. Thevalvepla-te is further provided with anopening 29'which is adapted "to register with the opening 23 in the top of the cover so as to admitatmospherie air through said opening into the chamber 7. The valve plate is providedupon its perimeter with a suitablefinger piece sowher'eb it may be conveniently turned or rotated to open or close communication between said chamber and the atmosphere. I

The device" as above described may be mounted upon theinstrument board of a motor vehicle by any suitable means, such, foi-instmc'e', asthat shown and described in my rice application for patent. filed July 28', 1917; Serial No. 183,317; It is, however, to be understood that any other deslred means may be employed for this purpose, and that the device may be mounted'or arranged upon any convenient part of the vehicle body;

From the foregoing description, taken in connection with" the accompanying drawing.

the construction and manner of operation of thef'device will be fully understood. Thus, for 1nst'ance,when the engine is operated at a high speed, the valve plate 26 may be rotated todispose the opening therein in registration with the opening 23 so that, in the suction stroke of the engine pistons, a partial va'cu'ui'n' will becreated in the chain her 7 and atmospheric air drawntinto said chamber. Thisairpasses through the porousniaterial 18 within the chamb'er'so that it' is relieved of all foreign matter, and thence through the bores 8 and 11 to the stem 14 and into the conducting pipe 15 Wl'llClYdGllVBIS the air into the gass upp'ly conduit or manifold. In passing through the passage or bore 11, the air is broken up or atomized by impact the point of operator may pour a "small quantity of gasolene through the opening-29 of the valve plate into the'chamber 7 Thi's 'gaso lene isdrawn through theporous material l9 and in it's passage through the perforated" late 10 and pa-st'thestem '13,iS atomized.

Thus proper combustion will be facilitated so that the engine 'inay be quicklystarted. Also, when the engine cylinders become overheated and preigniticn of theeharge o'ccurs th'e cynndersmay'be cooled bysupplying fwater to the chamber 7- through the opening of the valve plate, said valv'e plate remainingopen so that water vapor and air may be drawnintothe cylinders: It will thus be appreciated that I have produced a" device which-is of great utility and convenlence in practical use and at the sani'e time 1s quite simple in its construction, as

well as positive "and reliable imoperationn The device possessesbut few parts which are veryfconipactly arranged so that'it will occupy butlittle'space'npon'theinstrument board or dash 'of-th'e vehicle." Ae -these 7 parts'likewise are of'relatively simple form,-

it will be appreciated that the= invention may be produced at 'sma'll manufacturin cost. I V s a While I have hereinshown and described the referred construction-end arran ement I of the several'eleiiie'nts, '-it is to lYeunderstood that the device'is' susceptible' o'f-nia-ny modifications therein and 1 therefore,- reserve-theprivilege of-resorting to all such legitimate changes" may be fairly embodied within the-spiritand scope-of the invention as claimed.

I claim: 7 a
